2 Claims.

This invention relates to new and useful improvements, and design, indispensing caps for bottles or the like, from which liquids are to bepoured.

One of the objects of the invention is to provide a device in the formof a cap to fit over the mouth of a bottle or other similar container soas to permit the pouring of the liquid from same without spilling orwasting any of such liquid.

Another object of the invention is to provide a dispensing medium or capfor bottles or the like which will enable the user of same to regulatethe rate of flow of the liquid from such container, said regulationbeing available without any loss of the liquid dripping or leakage.

A further object of the invention is the provision of a cap as describedthat is convenient and easy to attach to liquid containers and likewiseconvenient and easy to detach therefrom when desired.

The foregoing stated objects and others attained in the use of theinvention will be apparent from a reading of the description inconjunction with the drawing accompanying and a part of thisapplication.

In the accompanying drawing:

Fig. 1 is a view of the invention, showing the device for the greaterpart in cross-section and the base in perspective.

Fig. 2 is an elevation view in perspective of the neoprene bellows.

Fig. 3 is a view in perspective of the base part of the device whichserves as the cap part.

Fig. 4 is a cross sectional view of the base taken on line 4-4 as shownin Figure 3.

Describing the drawing more in detail: The numeral I refers to the spoutof rigid material which is movably joined to the upper portion of theneck 3 at the extending lower portion lA, the neck 3 being in bellowsform and of a material known as neoprene which is used because of itslow permeability to gas as compared to rubber, the lower end portion ofsuch neck being joined with the base or cap part 4 on the exteriorsurface of the cap at 6. A stem member 2 having threads 213 on its upperend surface and having its lower end portion in the form of a yoke withan outwardly extending lower edge 2A and is fixed upright within theupper end portion 6 of the base or can 4 by means of the extending edge2A engaging in the recesses 4B formed in the inner surface of theportion 6 of the cap.

A ball 1 is mounted on the upper end of the stem 2 by means of thethreads 2B, such ball forming a valve means in the mouth of the spoutand said spout having a slanting outer edge to form a pouring edge. Theupper portion of the base has concave walls which reduces thecircumference of the upper edge in relation to the lower edge of thebase or cap. The lower portion of the base is provided withcircumferential threads 4A in its inner surface as a means to engageover the threads on the neck of a bottle or like liquid container and isprovided with an air vent 8 as a means for equalizing the air pressurewithin such bottle or container during the pouring out process so as tofacilitate the flow. of the said liquid out of the container.

In the operation of the device, it is first securely attached over theneck of a bottle or the like by means of the threads in the cap engagingthe threads on the neck of such bottle, or in the event such neck is notprovided with threads the cap is pressed down over the neck to hold samesecurely on the neck by means of friction exerted on the neck of thebottle. The container is then. grasped with one hand and the spout isdirected into a pipe such as the oil pipe on a motor vehicle, then byexerting downward pressure on the container the neck will shorten byreason of its bellows form and the contact of the extending part of thespout with the top of such pipe. As the bellows shortens the mouth ofthe spout is drawn away from the ball I, or valve, permitting the liquidfrom the said bottle to flow out past the ball and into the pipe inwhich the spout is inserted. When the pressure on the container isreleased the neck by reason of its resilient quality will automaticallyreturn to its normal position and the spout to its normal positionaround the ball, thus shutting off the flow of the liquid from thebottle, and any quantity of the liquid remaining in the space within thespout, neck and base will flow back into the container without anyleakage or loss of same. The opening 8 in the wall of the base or cappermits an equalizing of the air pressure within the device so as topermit an even flow of the liquid from the bottle or container.

From the foregoing description and operation as stated, it will beobserved that we have invented a highly efficient and useful device forthe purposes specified and, while we have shown the device in adesirable structure and form, the use of the device may requiremodifications without departing from the basic features or the spirit ofthe invention.

Having described my invention and its manner of operation, I claim:

-1. A device of the class described comprising a spout member of rigidmaterial and having projections extending outwardly from opposite sidesof its lower portion, a neck in bellows form with its upper end portionamxed to the inside surface of the lower end portion of said spout, ahollow cap formed base having the lower end portion of the said neckattached to the outer circumference surface of the upper end portion ofthe said base, a yoke-shaped member afiixed on the inside surface of theupper portion of the said base by means of its prong ends, a valve inthe form of a ball fixed on the upper extremity of the upward orvertically extending stem of the said yoke member, the said valvesealing the orifice in the spout when the spout is in its unactivatedposition, said valve adapted to unseal such orifice by reason of theshortening of said bellows neck by means of a pressure exerted on thesaid .4. spout projections, such pressure being applied in the directiontoward the said base, and the said valve adapted to return to itsunsealing position when the said pressure on the said projections isreleased.

2. A device as described in claim 1, said base member provided withcircumferential threads in the inside surface of its lower portion, andsaid threads adapted to engage the threads on the exterior surface ofthe neck of a bottle or the like.
